No, it's like Quote will never even find Booster. Frankly, what would be the point of that scene, if Quote was just to pass right through the room? And that's what Atra was going to do (which you would know if you read the whole thread). But, come to think of it...
Quote and Curly tag along the Labyrinth (it's in the script, right?), when they find professor Booster lying on the floor (just a minor script change for the sake of simplicity), apparently wounded. There's nothing they can do-WAIT! Wasn't that green guy a doctor? He could definitely patch Booster up, couldn't he? Our two robots get the professor to Dr. Gero's and receive a Booster pack as a thank-you gift, or to help them or whatever. The two go off to beat up the Core, and after Booster recovers, Gero tells him about that teleporter in that "AAAAAARGH GIANT BUGS RUN!!!" room we've seen earlier in the movie (surely the Shop, as there's no other Gaudi-inhabited room in the game). As Gero is the Gaudis' doctor, they let him and his guest through, Booster repairs the teleporter and POOF! He's rescued!
Now, the Gaudi don't know how to operate the teleporter, so they can't go eating all the delicious Mimigas. Or Booster just "repairs" the teleporter in a way that makes it break again after one use (he has no real tools, and it's badly damaged).
